In general, try to refrain from rubbing your eyes for at least a few weeks after LASIK as the newly healed LASIK flap may run the risk of getting wrinkled or worse still becoming displaced with over-zealous rubbing.
That said, it is advisable to refrain from rubbing altogether as eye-rubbing is a major contributor to developing astigmatism, or worse still, a condition called corneal ectasia which can manifest as a corneal disease called keratoconus, associated with thinning of the cornea and irregular eye power.
